China Electric Supply 6kv 10kv 35kV Oil Immersed Voltage
Transformer electrical distribution transmission
·Product introduction
It is with current transformer for measurement and protection, the
system is applicable to 50Hz power system line voltage is 35kV.
Product installation site for outdoor installation height of 1000m
above sea level, the maximum variation range of ambient air
temperature of -30℃~+40℃, but not suitable for installation in the
case of conductive dust with an anti-corrosive gas in.
It is suitable for power supply and distribution in coal mine, iron
mine, aluminum mine, copper mine, gold mine, silver mine, zinc
mine, titanium mine, oil field, gas field, oil and gas
station,explosion hazard gas etc.
S11 / 12kV fully sealed oil immersed power transformer shows the
advantages of low loss, low noise and high efficiency, which
achieves good energy saving effect and reduces pollution. Compared
with the traditional oil immersed transformer, fully sealed
transformer cancels the oil conservator. The change of oil volume
is automatically adjusted and compensated by the elasticity of the
corrugated sheet of the corrugated oil tank. The transformer is
isolated from the air to prevent and slow down the deterioration of
the oil and the aging of the insulation, thus enhance the operation
reliability. Normal operation is maintenance free.
· Structural features:
Our transformer is equipped characters as low loss, low noise,
strong protection for thunder and lighting, well anti-shortcut
capacity and fine appearance etc. It combines advanced equipments
and manufacturing process, and it has four remote functions: remote
communication, remote test, remote adjustment and remote control.
By remote control from a computer, the power station could be work
without any works on watch on the night. All our transformer has
passed the test by National Mechanical & Industrial Bureau and
National Power Company. The transformer is mainly used in power
network, and the projects of power distribution. 22kv distribution
transformer
Core equipped with advanced three steps: vertical and horizontal
and horizontal cut, lap and multi-stage. It disperses the air
distribution, improve the magnetic path. Decrease the no load loss,
no load current and noise. 22kv distribution transformer
Core adopts series measures dragged panel, pressed the coil,
particular glue for silicon steel to increase the strength of
mechanism. Power grid electric transformer
New structure of high and low voltage winding, reasonable
arrangement for oil tube and connection which increasing the
capacity of mechanical strength and anti-shortcut.
The tank is bell type or core suspension type, the wall of tank is
as wave form.
